In planetary science group, Oded Aharonson’s research covers a wide range of topics, not limited to surface and near surface, including lakes on Titan, cratering on all solid bodies and water on Mars. Bethany Ehlmann uses remote sensing and spectroscopic data of surface composition to understand the geologic evolution of panetary bodies, makes field and laboratory studies of aqueous alteration of Earth, and is heavily involved with JPL and Mars missions (MRO, MSL). Elsewhere in the Division, many faculty are interested in planetary research, especially for Mars. John Grotzinger is the project scientists of MSL and leader in the interpretation of sedimentological processes and history on Mars, John Eiler is interested in isotopic geochemistry, especially as applied to understanding origin and evolution of planets (including earth) and Mike Lamb studies surface processes, including Mars sedimentology.
